I have an aggressive sedum groundcover that has taken over a flower bed, invaded the lawn and seems unstoppable. Can you help?
The hardy nature of stonecrops grow into a dense mat and can be difficult to control.
Large areas of stonecrops may require the use of a herbicide.
Small areas can be removed by digging up the roots with a small trowel.
If you don't remove the roots, it will simply grow back.
For larger ares you will need to spray with a herbicide. Keep in mind that the chemicals will kill anything that it touches.
You may have to add a surfactant to the herbicide, since the plants have a waxy coating.
Repeat in a week to ensure all of the plants are treated.
